Abstract
The utility model relates to a roof lighting optical system. The roof lighting optical system comprises a dome, wherein reflecting mirrors are fixed on the outer side of the dome, and scattering mirrors are arranged inside the dome; solar rays are reflected through the optical system comprising the reflecting mirrors and the scattering mirrors, so that the rays are scattered below the dome through the dome; relative position of the sun is continuously changed in a day, so that the reflecting mirrors are obliquely arranged and are parallel to each other; and therefore, when the solar rays at any position irradiate, the reflecting mirrors can reflect the rays to the surfaces of the scattering mirrors between two reflecting mirrors, and then scattering rays are emitted out by the scattering mirrors. The roof lighting optical system has the characteristics of being simple in structure and good in lighting effect, the electrical energy is saved, and the cost is saved.
Description
Technical field
The utility model relates to a kind of optical system, relates in particular to a kind of optical system of roof lighting.
Background technology
along with people's continually developing solar energy source, to the utilization of sunshine also in continuous expansion, at some large-scale venues, sales field and exhibition centre, use sunshine to realize direct illumination, adopt simultaneously solar energy more to be applicable to the human eye vision effect, realize that with utilizing solar energy roof lighting compares, use electricity-saving lamp, the light fixtures such as LED lamp have the waste electric energy, therefore at present, illumination research for these occasion sunrays is also more and more, make a general survey of present or adopt the daylighting of light-transmission type plastic ceiling, adopt complicated light collection system daylighting, all can not better realize all good of cost and daylighting effect, therefore, when referring to ceiling area lighting, must realization namely save the illuminator that cost has again good daylighting effect.
Summary of the invention
In order to overcome the problems referred to above, the purpose of this utility model is to provide a kind of optical system of roof lighting, can take full advantage of solar energy, employing is by the dome that speculum and light-radiating lens are housed, after making the sunray reflection, fully introducing is indoor, and light illumination is provided, and has simple in structure, save electric power energy, save cost and the effective characteristics of daylighting.
To achieve these goals, the technical solution of the utility model is:
A kind of optical system of roof lighting comprises dome, dome outside installation speculum, and installed inside light-radiating lens, and whole formation is placed in building top layer 1 as ceiling.
Described whole dome adopts reverse V-shaped structure, and dome uses light transmissive material to make, and is convenient to light and sees through.
Described speculum is a plurality of speculums, adopts double-sided reflecting, and speculum tilts to be fixed on dome at a certain angle, and a plurality of speculums are parallel to each other.
Described each light-radiating lens is positioned at two speculum bottom center positions, is used for carrying out scattering to reflecting the light that comes.
Because the utility model takes full advantage of solar energy, adopt by the dome that speculum and light-radiating lens are housed, make the rear fully introducing of sunray reflection indoor, light illumination is provided, so have simple in structurely, save electric power energy, save cost and the effective characteristics of daylighting.
Description of drawings
Fig. 1 is a kind of optical system of roof lighting.
Fig. 2 is the light schematic diagram of optical system.
Fig. 3 is whole dome schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As Fig. 1, Fig. 2 and shown in Figure 3, my optical system of a kind of roof lighting of the present utility model comprises dome 2, and speculum 3 can be fixedly mounted on the outside of dome 2, dome 2 installed inside have light-radiating lens 4, dome 2 adopts reverse V-shaped structure, and the whole light transmissive material that uses is made, and makes light to see through, speculum 3 adopts double-sided reflecting, and between double mirror, mutually across a certain distance, and placements that be parallel to each other all can be reflected it when one side is faced sunray arbitrarily.A plurality of light-radiating lens 4 are arranged on the inboard of dome 2, and each light-radiating lens is positioned at two speculum bottom center positions, are used for carrying out scattering to reflecting the light that comes.
Operation principle of the present utility model is:
When using the optical system of roof lighting, can take full advantage of the nature sunray, by the optical system that speculum 3 and light-radiating lens 4 are installed, sunray is reflected, make light scatter to dome 2 belows by dome 2.Because the relative position of the sun in the middle of a day is constantly changing, therefore speculum 3 is tilted to install, and be parallel to each other, when being in like this sunray irradiation of arbitrary position, speculum all can be surperficial to light-radiating lens with light reflection between two speculums, then send scattered beam by light-radiating lens.
This optical system is only utilized speculum and light-radiating lens, just can form the not reflection of sunray in the same time, owing to scattering to dome below formation illumination.Because native system is simple in structure, save electric power energy, so be applicable to gymnasium, hypermarket, supermarket, high ceiling exhibition centre, industrial premises and other high ceiling industrial lightings.
